With the help of nearly ten thousand flying creatures and thousands of stinging pterosaurs, the dinosaurs and wolf cavalry finally felt better, had breathing space, and could begin to retreat orderly.

But as soon as they withdraw, the firepower guard and the pullout artillery will be unable to attack.

Because they need to go through the mental barrier to retreat, they will block the breach, and the energy bomb can only hit the mental barrier.

In fact, there is no way to withdraw, after all, they can not stay in the infected group for a long time, can only charge a wave to withdraw, a little delay time.

The infection group didn't pay too much attention to the retreating wolf cavalry and dinosaurs, which would not affect their attack anyway.

The wolf cavalry and the dinosaurs retreated, and they moved forward. Within a few seconds, they were within 30 meters of the westerly fortress.

This is a distance that can make both sides face to face. The rebel members in front can even see the ferocious expression on the infected body's face.

"The second echelon is ready to defend! The third echelon will take over and the first echelon will retreat! " The army quickly issued new orders.

Then the troll hunter in the third echelon threw out his bone spear and shot at the spiritual barrier in front of him.

The witch doctor and thunder rhinoceros who are a little behind also launch their long-range attack. Although the number is relatively small, they also want to contribute to the battle.

The melee dinosaurs in the second echelon began to sharpen their claws and showed ferocity in their eyes. They had been waiting for a long time to fight.

As most of the wolf cavalry and dinosaurs retreated into the sky, the firepower guards and artillery were able to open fire, pouring all the ammunition into the mental barrier and the infected population.

Under the attack of many parties, the mental barrier of the corpse controllers was broken again and dissipated in the air.

Unfortunately, it broke up a little late, because the infection group had already touched the sky of the westerly fortress, and began to attack the barrier to protect the westerly fortress.

"Second tier, attack! Beat them back The passers-by yelled through the short-range communicator.

At the next moment, all kinds of dinosaurs in the second echelon took several steps forward, either killing or pushing back the common infected body close to the sky.

However, as soon as the infectious body rushes forward, it will keep flowing, with tens of millions of followers.

It's hard to beat them back even with the firepower guard and the pull gun plus the second tier of dinosaurs.

Generally, as soon as the infected body in front of us is killed, the left and right sides will catch up with us again. When we attack the left and right sides, we can't hold on to the front.

So as time goes on, more and more common infections attack the sky.

If you look down from a high place, you will find that the sky is like a "ball", and a quarter of the surrounding area is surrounded by infected bodies.

These infected bodies desperately attack the sky, as if to blow up the "ball".

"Boss Lu! The protection value of the sky screen is rapidly decreasing. The estimated defense time is 1.02 points! " A member of the rebel forces reports to the army through a short-range messenger.

"OK, I see. Keep watching." Looking at the battlefield, the army replied.

Although it sounds like the sky screen can resist so many infections for an hour, it's a long time.

But the road army is very clear that it's just an attack by ordinary infectious agents, and the mutated infectious agents haven't been launched yet

Although they can't kill any of them with the attack of ordinary infectious agents, it's not their purpose to be trapped here. They can't go back now.

Moreover, the distance between the mutated infectious bodies and them is not very far. If the corpse controllers want to deliberately target them and send the mutated infectious bodies to besiege them, they will definitely suffer heavy losses.

Fortunately, at this time, Triceratops and Touchui dragons came up in time, and they also started dragon skills one after another, hitting the spiritual barrier in front of them.

In terms of individual strength, they are all A-level, much better than the overall C-level wolf cavalry and frost wolf. They are absolutely strong enough in the charge, and soon break the spiritual barrier below.

After killing the front group of common infectors, they also entered the infected group and joined the trapped wolf cavalry.

With the help of dinosaurs, the pressure of the wolf cavalry is much less, from the previous can't turn away to be able to move a little bit.

Finally, the firepower guard and the pulling gun of the party can also attack the common infected body through the breach of the mental barrier, saving ammunition and causing damage to the infected body group at the same time.

As for why these defense facilities can only hit ordinary infectious agents in the chaotic battlefield without accidental injury, the reason is also very simple.

That is, there are reconnaissance guards, just like a large radar, or some artificial intelligence radars, which can help them to lock the position of every common infectious agent without any deviation.

Even the number of energy projectiles fired per second, the direction to be fired and the firing speed will be calculated.

Therefore, when the investigation guard gives the attack order, the firepower guard and the pulling gun will not make mistakes naturally.

But even with firepower and artillery, dinosaurs and wolf cavalry were in danger.After all, their task is to charge, and many of their abilities can only be brought into play by charging.

Now that we are trapped in the same place, our combat effectiveness has been directly reduced by two-thirds. In the face of the siege of so many infectious agents, it would be good if there were no serious casualties.

Most importantly, although there are no deaths yet, it doesn't mean there will be none later.

Because the remote corpse controllers have already responded and are ordering the mutant infectors to come here, including lickers and splitters, as well as a large group of elite infectors.

It's a good thing to say that the elite infection can be solved by Wolf cavalry and dinosaurs, even tens of thousands of them.

But if they are approached by long-range attacking creatures such as lickers and splitters, they will have no counter measures, and heavy losses are inevitable.

This is the disadvantage of rashly entering the infection group. It's easy to enter, but it's difficult to go out.

Knowing that the situation was not quite right, the army quickly gave the second order: "Xiaowan, you also take your mutant creatures to help fight. You must help them out and cover them. I can't use them for the time being."

This is the only way for the road army to help the dinosaurs and wolf cavalry at present, because the second and third echelons have to defend behind the sky and can't move.

"Got it!" Xiaowan gave a simple reply.

Then, tens of thousands of flying creatures and thousands of pterosaurs flew over the heads of the people, reached the top of the infected group from the breach of the spiritual barrier, and attacked the infected group with the advantage of position.
